Description

Upgraded 2D Space Shooter to NGO 1.8.1

• added the new Rpc attribute
• added OnConnectionEvent

I DID NOT add the new InstantiateAndSpawn to it yet. I tried to add it to the Spawner.cs script, but it did not work well due to a NetworkObjectPool being used
e.g. GameObject go = m_ObjectPool.GetNetworkObject(m_AsteroidPrefab.gameObject); does not work. I am not sure if I should include InstantiateAndSpawn here?
